Embodiment Construction

[0035] Construction process and key points of operation

[0036] 1. Construction process

[0037] Construction preparation → reinforcement installation and acceptance → design and reservation of formwork bolts → installation of bolt sleeves and internal screws → formwork installation and positioning → installation of external screws → reinforcement of formwork with internal and external corrugations → concrete construction → removal of external screws and formwork → removal of sleeves → alignment Concrete sleeve holes are treated.

[0038] 2 Operation points

[0039] 3 system composition

[0040] The core of the detachable water-stop bolt construction method is the detachable water-stop bolt. The detachable water-stop bolt is mainly composed of a sleeve, a concrete inner screw and an outer screw. Nuts, etc. work together to form an effective reinforcement system.

Abstract

The invention relates to a combined detachable water-stop bolt and a construction method thereof. The combined detachable water-stop bolt comprises screw rods. The combined detachable water-stop bolt is characterized in that two ends of a middle screw rod are respectively in threaded connection with screw rods through sleeves and are respectively provided with threads, and the middle screw rod is provided with a water-stop piece; the sleeves are of a circular table shape, the diameters of the outer sides of the sleeves are larger than the diameters of the inner sides of the sleeves, and sleeve inner walls which penetrate through the upper and lower surfaces and are provided with screw threads are arranged in the sleeves; internal hexagons for detaching the sleeves are arranged on one surfaces, with the larger diameters, of the sleeves, and templates are respectively fixedly arranged on the one surfaces, with the larger diameters, of the sleeves; square timbers are mounted on the outer sides of the templates, steel pipes are mounted on the outer sides of the square timbers, and butterfly buckles are mounted on the steep pipes and are connected with the screw rod on the outer side.

Description

technical field [0001] The invention relates to the construction field, in particular to a combined detachable water stop bolt and a construction method thereof. Background technique [0002] At present, most buildings in my country have waterproof requirements. Waterproof bolts are usually installed to reinforce the formwork during the construction of waterproof exterior walls. After the concrete pouring is completed, the bolts protruding from the exterior wall are cut off by gas welding, and then the concrete surface is treated with cement mortar. flat. Since the bolts protruding from the wall need to be cut off, the amount of construction work will be increased; gas welding is used during operation, which is an open fire operation, and fire protection requirements are added to the engineering construction; the cut bolts are usually unable to be recycled, resulting in waste of materials; The concrete surface is more difficult to handle, which reduces the quality of concr...
